The Great Heat Solar Term: How Shanghai Tangke Uses 'Technological Membrane Power' to Break Through the High Temperature Predicament

It was extremely hot, and the heavens and the earth were like furnaces. When the cicadas sweep through the city with a heat wave, and when the cold chain logistics is facing extreme challenges under the scorching sun, the aluminum-plastic composite packaging technology of Shanghai Tangke New Material Technology Co., Ltd. is quietly becoming the "invisible armor" to protect the safety of food and industrial products. 

During the summer season, the temperature in many places in China exceeded 40°C and the humidity exceeded 80%, forming a "cooking mode".  In this environment,Food deterioration accelerates: the reproduction rate of bacteria increases by 3 times, and the spoilage rate of fresh fruits and vegetables surges; Moisture in electronic components: humidity causes oxidation of the circuit board, and the failure rate of precision equipment increases; Chemical raw material agglomeration: Water penetration leads to powder solidification, affecting industrial production efficiency. 

However, traditional packaging is prone to three major pain points: barrier failure, static electricity accumulation, and physical damage under high temperature and high humidity, and it is urgent to break the situation with material technology. 

Shanghai Tangke's latest patented technology in 2025, aluminum-plastic compositeton bag material （Lightweight design: The material thickness is only 0.15mm, which is 40% lighter than traditional ton bags, reducing transportation carbon emissions;Recyclable process: TPU elastomer improves the reuse rate of the bag body, and a single bag can be used up to 12 times, which is in line with the ancient motto of "saving materials and making use of materials"2;Source consumption reduction: The German W&H blown film line accurately controls the temperature, reducing production energy consumption by 33%, echoing the oriental wisdom of "calm and naturally cool" in the summer.） , faces the challenge of the heat through innovative structural design such as armor protection, water locking and moisture resistance, fatigue resistance and anti-rubbing, and static dissipation. 

When the fresh truck breaks down on the 40°C highway, the aluminum foil insulation layer of the Tangke ton bag can make the internal temperature rise by only 2°C in 2 hours (the ordinary bag heats up by 12°C), winning rescue time for high-end ingredients such as salmon and steak. With metallocene polyethylene sealing layer, it blocks oxygen penetration and reduces the spoilage rate by 67% 

Chemical fertilizers are easy to absorb moisture and compact at high temperatures, and the linear low-density polyethylene lining of Tangke ton bags is fluorinated to form a "lotus leaf effect" that water molecules cannot penetrate, so that diammonium phosphate remains loose and particulate after 30 days of storage in the open air. 

When the "ice mirror" recorded in "Zhou Li" evolved into today's nanocomposite film, what remains unchanged is the ingenuity of human beings to cope with the heat. Shanghai Tangke uses the "PET-aluminum foil-PA-PE" quadruple barrier (patented laminated structure) to reconstruct the balance of yin and yang in the microscopic world of materials - aluminum foil reflects the sun as "yin", and TPU is flexible and compressive as "yang", just like the survival philosophy that people need both coolness and resilience in the summer season. 

Just like the German film blowing line (4,000 tons/annual production capacity 2) rotating at a uniform speed in the workshop, the dialogue between science and technology and nature has never stopped, and the fire of innovation is hotter than the scorching summer sun.
